Masked Crab - Corystes cassivelaunus

The Masked Crab, Corystes cassivelaunus, is widespread around the UK on sand. It is not often seen by divers as it spends daylight hours under the sand with its antennae just emerging. It uses these to channel water down its gills and emerges at night to feed. The body is quite small, maybe about 4cms across but with disproportionately large claws
